Quoted from mjmpin:thanks, can you share a bit how the switch test works - I thought it was simple like light tests
but I am not sure what I am looking at or looking for on the display
and there are two different switch test menu items on the spike 2 - one of them I can't even get to switch 63
sorry to bother, but sounds like you have done this, I've never tested a switch from software
Sure...it is one of the most often used and helpful tools you can use to diagnose issues. It lets you see if one specific part of the game is working without the complexity of all the other stuff going on that happens when you play a game.
To test the opto exit switch, first you need to lower the building. You do that with the menus, but I'm not in front of my machine so I can't spell out the steps. Let me know if you have trouble with that part.
Then, you need to test the switch.
This document is quite good: https://www.gameroomguys.com/grg-site/how-to-docs/How-to-Pinball-Switch-Test.pdf
Once you get to step 5, close the coin door.
On step 7, it says to "press the lockdown switch." Do that so you can see how the switch test works.
Then, take a ball, roll it under the building into the VUK. The VUK will kick it up and then the ball will roll past the exit opto. You should see that on the screen. Do that a lot of times (~25) and see if it registers 100% of the time. If it is anything less than 100% of the time, you have an issue with that opto.
Let us know how it goes...
